I think the letter of 3 May 1979 was written primarily from a NH perspective. One sentence you didn't include was; "because I usually take an extended holiday in spring or early summer I do not make a list for the Flat". That said, the idea of identifying a list of horses to follow on the Flat on not wholly dissimilar lines to that VDW suggested has been and remains a mainstay of my approach.
Elsewhere, VDW implied that there were differences between NH and Flat that, for example with respect to ratings, require "minor modifications". I think there is a major difference - Flat horses in general progress (and eventually become regressive) differently to NH ones, especially chasers, who are often at their peak at an age when most Flat horses are regressive.
Taking that difference into consideration, on the Flat it is always good where a horse has, as VDW put it in the letter you partly reproduce, "proven ability". But with younger horses a degree of progression can reasonably be assumed. Thus when each winter I select a handful to follow the following year, with the younger ones I am happy to assume that a degree of improvement over and above the level of ability already proven can be expected.
With handicappers, I think VDW's advice about placings is largely irrelevant. While a sequence of placings is not uncommon, neither is a more "erratic" pattern as connections seek to prepare their horses for future wins by placings that may not be altogether unrelated to the wish for a lower OR. (Both Intrinsic Bond and Mountain Peak, who have run over the last few days, almost certainly have specific seasonal goals the achievements of which would not have been made more likely by winning relatively minor races at this stage.)
I think the winning selection Mick made at the weekend, Ready Freddie Go, together with Mid Minster in the same race, are good examples of the sort which one might follow on the lines of VDW's approach, though neither was on the list I made in December.
Both had won reasonable handicaps in 2022, and indeed in 2021. On Saturday both were running in races of similar or lower class to their last wins. Both were running off lower marks than their last wins for the first time since those wins. Both had on Saturday conditions over which they were proven. Assuming neither was yet regressive (and with RFG that was unlikely; more likely with M but he was progressive as a 6yo), they were prima facie possibles for Saturday's race which, in my view, they hadn't been in their earlier races this year.
Neither was a consistent horse in the crude VDW terms of last three placings, but the careers of both since their 2022 wins seem to have been to get them back to winning marks.
I think "fraud" is a little harsh re VDW. We are all but certain he wrote under his name and as "VDW", which is tricky, but hardly fraud. And the fact that as far as we know he never proved any of his claimed selections before the races gives reason for scepticism but again is hardly fraud. I am sceptical about his claims, but have learnt so much from his writings and nothing in any of the more recent "how I do it" books by the likes of Nick Mordin, Alan Potts or om Segal comes close to the range of ideas and possibilities the VDW material holds.
